I seem to have an issue with my replicated setup.
The master says no rebalancing is happening, but the slave says there is (sort of). The master notes the issue:
[2015-06-05 15:11:26.735361] E [glusterd-utils.c:9993:glusterd_volume_status_aggregate_tasks_status] 0-management: Local tasks count (0) and remote tasks count (1) do not match. Not aggregating tasks status.
The slave shows some odd messages like this:
[2015-06-05 14:44:56.525402] E [glusterfsd-mgmt.c:1494:mgmt_getspec_cbk] 0-glusterfs: failed to get the 'volume file' from server
I want the supposed rebalancing to stop, so I can add bricks.
Any idea what is going on, and how to fix it?
Both servers were recently upgraded from Fedora 21 to 22.
Status output is below.

This is weird. Did you start rebalance yourself? What does "gluster volume rebalance volume1 status" say? Also check if both the nodes are properly connected using "gluster peer status".
If it says completed/stopped, you can go ahead and add the bricks. Also can you check if rebalance process is running in your second server (xena?)
BTW, there is *no* master and slave in a single gluster volume :)
